doses anyone happen to this? please let me know your solution, Thanks!

zawlin · 2016-08-26T07:39:06Z

try adding caffe.reset_all(); to fcn_tracker.m just before caffe.set_mode_gpu();. at least for me the memory keep running out because each call of the script recreate the entire network and the matlab engine keep crashing, that's why you see this error.

myfavouritekk · 2016-08-26T08:35:37Z

@zawlin Right. reset_all() will clear stand-alone nets in the GPU. I think adding reset_all() for each fcn_tracker call may solve this problem, but it requires loading VGG for each tracking process and may takes a lot of time compared to tracking itself. Probably should call rest_all only when restarting a matlab engine. What do you think?

zong209 · 2016-10-12T03:31:22Z

I got the same error. I try to add caffe.reset_all; in fcn_tracker.m, but the same crash happened. I try to add it in track.py by matlab_energy(), but I am failed. Now I don‘t know how to solve it.

My GPU is GTX960M with 2GB, is it the reason? Does it mean that I should use an another caffemodel ？

myfavouritekk · 2016-10-20T02:56:47Z

@zong209 what is matlab_energy?

zong209 · 2016-11-29T11:26:03Z

I'm sorry, I didn't express it clearly @myfavouritekk . I actually try to add reset_all(); before matlab.engine.start.
For above problem, I changed my GPU into GTX1080, then added caffe.reset_all(); before caffe.set_mode_gpu(); in fcn_tracker.m. The crash didn't happen again.

Jensen-Su · 2016-12-29T11:05:52Z

I've tried adding caffe.reset_all(); before caffe.set_mode_gpu(); in fcn_tracker.m right as what @zawlin @myfavouritekk and @zong209 suggested. And my GPU is TITAN X with 12GB. But nothing changed, why?

mingde510 · 2017-01-23T11:42:25Z

I added caffe.reset_all(); before caffe.set_mode_gpu(); in fcn_tracker.m, the problem had not solve,
Can you help me?@myfavouritekk

EswarSaiKrish · 2018-04-04T04:09:55Z

@mingde510 or anyone else, were you able to solve this issue finally ?
I am using a GTX 1060 6 GB Variant and I get the same issue as this thread, MATLAB process cannot be terminated.

I have tried adding caffe.reset_all(); in fcn_tracker.m just before caffe.set_mode_gpu(); like @myfavouritekk, @zong209 has suggested, but my terminal output says Cleared 0 solvers and 0 stand-alone nets
And then I get the same error.

Anyone has any success??
Thanks.
